Embodiment Construction

[0051] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0052] The invention provides a method for controlling the roof support of a hydraulic support group. The method implements the establishment of a system-level model of the hydraulic support group through a conditional random field graph model, and then realizes the prediction of the roof support decision of the hydraulic support group.

[0053] Method of the present invention comprises the following steps:

[0054] 1. Establishment of conditional random field graph model of hydraulic support group

[0055] According to the characteristics of the spatial distribution and action timing of the hydraulic support group, the optimal decision-making model is abstracted into a graphical model, as shown in Figure 3.

[0056] The conditional random field is the conditional probability distribution P(Y|X) that outputs the Markov random field Y...

Abstract

The invention provides a top plate support control method of a hydraulic support group based on a graph model, wherein a storage medium makes a decision on the control process of the hydraulic supportgroup through the graph model. The decision-making results are based on two factors: one is the self-decision of a single frame, the other is the relationship between frames. The self-decision of a single frame is predicted by depth neural network, and the correlation between frames is determined by the pair potential function of graph model. The invention provides a system-level model for the action decision-making of the hydraulic support group, the hydraulic column and the shield beam, and the decision-making process is also completed at the system level, which is more conducive to the safety support of the fully-mechanized top-coal caving face.

Description

technical field [0001] The invention relates to a method for controlling the roof support of a hydraulic support group, in particular to a method for controlling the roof support of a hydraulic support group in a fully mechanized caving working face based on a graphical model. Background technique [0002] At present, the roof control method of the downhole hydraulic support is completed manually, and the operator sets a fixed initial support force according to experience to make the hydraulic column rise. When there are unfavorable situations such as the lowering of the side and top coal, manually operate the cover beam and hydraulic column of the hydraulic support to make corresponding operations. Manual operation cannot comprehensively consider the overall dynamic status of the roof of the working face, and cannot effectively take into account the performance of the working face level, let alone realize the automatic control of the hydraulic support group. The root cause ...
